The city was founded in 1831 by Martin Boots and David Branson who each donated 30 acres of land to develop a city by the flowing Mississinewa River, after nearly 20 years of settlement following the bloody, victorious historic Battle of the Mississinewa of 1812. Marion developed slowly as an agricultural trading center with supporting farm and forest industries until the 1880s when a huge supply of natural gas was discovered in Grant County and much of east-central Indiana, creating the Gas Boom, drastically propelling growth, and impacting the course of its industry and economy.
Marion and Grant County Historian, William Munn, led a project with Marion students to research and outline Marion’s history. If you would like to read a thorough history of Marion, visit:
